of the United States, residing in the borough "W T T SEA E T orr oe-g i AM E or'n'sw izonk, N. Y." i I .f tosuna I Be.it known that I, J AMES A. Nan, a citizen of Brooklyn, county of Kings,'city and State". of New York, havein'vented a certainnew and, useful Improvement in Closures, of whichthe following is, a'specificatiom The object I have inview is the production of a. closure for bottles, jarsfan'd the like which comprisesa strong and rigid structure which will secure a perfect seal and yet at the same timeqmay be readily opened and will have no separable parts which may become :lost or projections which may become broken.

.Another object is to produce a closurewhich after.being. once opened may be continued to be used upon the, same-receptacle and a seal' secured; I v g a I attain these objectsby the mechanism illus-. trated in the accompanying drawings, which show one embodiment otmy invention.

In all the views like parts are designated In carrying'out my invention I provide a cap 1,.formed of sheet metal, having a flange 2. Thisfiange'is continuous and is preferably made integral with thecap,and it is pro-- vided with vertical-lugs 3 3, struck up out of the metal, These lugs are preferably in the form'of hollow cylinders having closed tops,

and the tops are indented at 3 in the process of manufacture for the purpose hereinafter explained. The lugs are preferably formed integrally with the flange, each being closed at the topand openat the bottom. These lugs are arranged so that-their sides may be ruptured, and they will betherebydestroyed and the continuity of the flange thereby broken. The presence of the lugs'does not, break the continuity of the flange, which remains uncut or unmutilated where the lugs are located, andthe flange will be unweakened at these points. The lugs are placed on the side .of the medial line of the cap-that is to I Specification of Letters Patent. I Application filed March 31,1905 Serial No 253,171.

I say, lhey are in such position thatastraight line ('rawn across the topof the cap to connect them wouldextend across and to one side of the center of the cap.

The fiange 2 is provided with an insetipor tion 4:, adapted to engage under the head 50f the neck of. the receptacle 6, which is being covered and which constitutes a means 'for en gage ment-with the receptacle. This "inset portion 4 extends around the flange from one lug to the other around thelonger way, so

that more than half of the circumference'of the flange will be provided with theinset portior, as shown in the drawings. In thatp'or tion of the flange between the lugs opposite" to the inset portion 4 is provided a secondinset portion 7 for engagement with the-bead 5.- This; inset portion extends around the flange but a short distance, and extending be-- finger-piece 8, thus constituting a.

The closure is applied to the receptacle to. I

be covered before the'inset portions are made.. theinset portion being forged against the-nu der surface'of the bead by anysuitable rneans'l.v When thus secured, a perfectseal is provided. I

To open the closure, the tine'ofai fork or I other suitablemechanism isintroduced within the top of the lugs 3 v3-,puncturingthem at the points indicated by the indentations 3,

and the side'sof the lugs are then broken, so

that they-will be destroyed. JIhedestruction of the lugswill break the .continuity of .the'

flange 2. The finger -'fpie'ce. 8,may then be used to disengage the inset? from the bead, and the cover may be bent upward orflexed across along the line9 9, as shown in'Fig. 6,

elevating one side of the cover. [With this portion elevated the closure may thenbe removedfrom the receptacle by sliding it in the direction indicated by the arrow in Fig, 6,, the elasticity of the metal permitting the flanges 2 to separate' {sufiicient distance to disengage the inset portionse from the bead. The

closure may here-applied to the receptacle by IOC reversing this operatign-that is to say, by

first moving the closure to cause the flange and its inset portion to engage with the bead and then flattening down the top to cause the inset portion 7 to en'gage'with thebead. The

taole, and the cover willbe secured in place.

is placed within the closure and assists in percover when reapplied will form-a seal, which": will serve to protect the contents of. the recepY- fecting the seal and also serves to'protect the l contents of the receptacle from contact with the under side of the closure.

The closure may be removed and reapplied a number of times without breaking the metal across the flexure. By using a flange formed with lugs acontinuous flange is secured, which will produce an entirely rigid structure, so that a perfect seal'can be produced, and the cap will be rigidly secured to the receptacle, so that there will be no opportunity of leak,- age by the breaking or expanding of the flange.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. An improved closure which comprisesa cap with a flange, inset portions on the flange adapted to engage with a receptacle and lugs on the flange which when ruptured will permit the cap to be flexed and the insets disengaged.

2.. The combination with a receptacle, of a cap having a continuous flange unweakened at any point and inset portions engaging with the receptacle, and means on the flange whereby its continuity may be broken and the cap permitted to be flexed.

3. An improved closure which comprisesa cap with a continuous unweakened flange, means carried by the flange for engaging with a receptacle and means to permit the flexing of the cap to disengage it from the receptacle.

4t. An improved closure which comprises a cap with a flange, means carried by the flange for engaging with a receptacle and lugs on the flange which will break the continuity of the flange by being ruptured and permit the flexing of the cap.

5. An improved closure which compris'esa cap of sheet metal with an integral flange, lugs on the flange on thesarne side of the medial line, inset'portions on the flange hetween the lugs, and a fingerpiece on the flange.

6. An improved closure which comprises a sheet-metal cap with a flange, means carried by the flange to permit the rupturing of the flange and breaking its continuity, and an in set portion on the flange adapted to engage with a receptacle and extending between the rupturing means and more than half oi the circumference of the flange, and a second inset and finger-piece on the flange between the rupturing means and opposite the first inset.

7. An improved closure which comprises a sheet-metal cap with a flange, lugs on the flange, which upon being ruptured will break the continuity of the flange, and an inset portion on the flange adapted to engage with a receptacle and extending between the lugs and more than half of the circumference of the flange, and a second inset and linger-piece on the flange between the lugs and opposite the first inset.

I 8. An improved closure which comprises a cap with an integral continuous flange, inset portions on the flange adapted to engage with a receptacle and means on the flange which when ruptured will destroy the'continuity of the flange,'the said flange heing'unweakencd adjacent to the rupturing means.

9. An improved closure which comprises a cap with a flange, inset portions on the flange adapted to engage with a receptacle and lugs on the flange which when ruptured will permit the cap to be flexed and inset portions disengaged, the said lugs having inset tops.

This specification signed and witnessed this 30th day of March, 1905.
